Description

RF speed sensors offer low speed response, no drag, large air gaps and sensing characteristics which enable this type of speed sensor to sense non-ferrous metals like aluminum or nonmagnetic stainless steel in addition to ferrous metal. Unlike their VR counterparts, an RF speed sensor is not a passive device and requires coupling with a signal conditioners/preamplifier. These devices produce a digital square wave output versus the analog sine wave of the VR speed sensor.
